[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Figure 1 This is a schematic diagram of the portable device for releasing black egg wasps of the corn moth in cornfields, as per this utility model. Figure 1As shown, the device includes: a release box 6 and a vertically arranged support rod 1. A box cap 4 is provided above the release box 6. The box cap 4 and the release box 6 are connected by a connecting rod 5. One corner of the box cap 4 is movably mounted on the support rod 1 and can move up and down along the connecting rod 5.

[0021] Specifically, traditional bee card release devices are often susceptible to rain, which can damage the eggs or adult wasps of the noctuid moth on the bee cards. The cap 4 design in this application plays a crucial protective role. When rain comes, the cap 4 can cover the top of the release box 6, effectively preventing rainwater from directly wetting the bee cards and the noctuid moth wasps on them. In addition, the space between the cap 4 and the release box 6 also provides a certain buffer, reducing the possibility of rainwater seeping in through gaps.

[0022] Furthermore, prolonged exposure to direct sunlight and excessively high temperatures can negatively impact the emergence of the black-egg wasp of the noctuid moth. To address this issue, the cap 4 of this application not only provides rain protection but also offers some degree of sun protection and temperature control. When the sun is strong, the cap 4 can block direct sunlight, lowering the temperature inside the release box 6. Simultaneously, the space between the cap 4 and the release box 6 helps create a small microclimate, regulating temperature through air convection and other mechanisms, making the environment inside the release box 6 more suitable for the growth and emergence of the black-egg wasp of the noctuid moth.

[0023] Furthermore, traditional card release devices often lack portability and adjustability, making them difficult to adapt to usage needs in different environmental conditions. The device provided in this application, by movably mounting one corner of the cap onto the support rod, integrates the cap and release box via a connecting rod, allowing both the cap and release box to be adjusted in height simultaneously on the support rod as needed, achieving a perfect combination of portability and adjustability. The support rod 1 not only provides stable support for the entire device but also allows the user to adjust the device's height as required.

[0024] The portable device for releasing fall armyworm egg wasps in cornfields provided in this application not only effectively solves the problems of traditional wasp release devices being susceptible to rain and high temperatures caused by direct sunlight, but also improves the field application effect of fall armyworm egg wasps. At the same time, the portable and adjustable design makes the device more flexible and easy to use, adapting to the needs of different environmental conditions, and providing a new solution for the control of pests such as fall armyworm.

[0025] Furthermore, the cap 4 has a triangular pyramidal structure.

[0026] Specifically, the triangular pyramidal structure has a wide top and a gradually narrowing bottom. This design allows rainwater to quickly slide off when it falls onto the cap, reducing the possibility of rainwater accumulating on the cap's surface. Therefore, even in heavy rain, the cap 4 can effectively protect the release box 6 from rainwater, thus ensuring the safety of the black-egg wasp. Furthermore, the triangular pyramidal structure of the cap 4 can more effectively block direct sunlight. Due to its wider top, it can cover a larger area, reducing the chance of direct sunlight hitting the release box 6. Moreover, the conical side design helps guide airflow, forming a micro-ventilation system that helps regulate the temperature inside the release box 6, preventing black-egg wasp emergence problems caused by high temperatures.

[0027] Furthermore, the top of the release box 6 is provided with a mesh box top 8, and a nutrient supplement cotton 7 is placed inside it.

[0028] Specifically, the mesh structure allows for free airflow, helping to maintain a suitable temperature and humidity inside the release box 6, providing a comfortable living environment for the black moth wasp. The box top 8 is composed of 80-mesh nylon mesh, giving it excellent permeability. Due to its small aperture design, it prevents the black moth wasp from being damaged by external factors while allowing the wasps to freely disperse into the field after emergence. This ensures the effectiveness of the release device when used in the field.

[0029] The nutritional supplement cotton 7 is rich in nutrients required by the black-egg wasp of the noctuid moth, such as sugars and water, which helps meet the nutritional needs of the adult wasp after it emerges. The nutritional supplement cotton 7 can also absorb and retain a certain amount of moisture, creating a suitable humidity environment inside the release box 6, which is conducive to the healthy growth of the black-egg wasp of the noctuid moth.

[0030] The portable device provided in this application, through the design of the mesh box top 8 and the nutrient supplement cotton 7, provides a more suitable, safe and efficient living environment for the black egg wasp of the noctuid moth, which helps to improve the effectiveness and stability of the release device when used in the field.

[0031] Furthermore, a honeycomb card insertion port 9 is provided on the side of the release box 6, and a mesh cover is provided on the honeycomb card insertion port 9. The mesh is fixedly connected to the side of the release box 6 by a zipper.

[0032] Specifically, the design of the bee card insertion port 9 allows users to easily insert the bee card into the release box 6 without complicated operations or tools. Simultaneously, the zippered mesh cover can be easily opened and closed, facilitating users to replace or check the status of the bee card at any time. Furthermore, the mesh cover is fixedly connected to the side of the release box 6 via a zipper, forming a closed space that effectively prevents direct impact from external factors such as rain, sunlight, and wind on the bee card. This helps keep the bee card dry, cool, and stable, extending its service life. In addition, because the mesh cover's aperture is designed to be small enough, it prevents the bee card from being damaged by external factors while allowing the black moth egg wasps to freely disperse into the field after emergence. This ensures the safety and effectiveness of the release device when used in the field.

[0033] Furthermore, a humidity replenishment box 10 is provided below the release box 6, and a cotton ball 12 that has been soaked in moisture is placed inside the humidity replenishment box 10.

[0034] Specifically, humidity is one of the key factors affecting insect growth and development. The thoroughly soaked cotton ball 12 within the humidity replenishment box 10 continuously provides a stable and moderate humidity to the release box 6 and its internal environment. This is crucial for maintaining the vitality of the black-egg wasp and promoting its normal growth and development. In field environments, the inside of the release box 6 may become too dry due to factors such as sunlight, wind, and changes in soil moisture. The design of the humidity replenishment box 10 effectively prevents this from happening, ensuring that the inside of the release box 6 always maintains a relatively humid environment, which is beneficial to the survival of the black-egg wasp. The thoroughly soaked cotton ball 12 slowly releases moisture, thus prolonging the effect of humidity replenishment. This means that users do not need to frequently replace or replenish water, reducing operational difficulty and maintenance costs.

[0035] Furthermore, a cotton ball inlet 11 is provided on the side of the humidity replenishment box 10. The diameter of the box cap 4 is twice the length of the release box 6. The support rod 1 is a cylindrical plastic structure. The box top 8 is composed of 80-mesh nylon mesh; the four sides of the release box 6 are composed of 120-mesh nylon mesh.

[0036] Furthermore, a fixing block 2 is provided at one corner of the box cap 4, and a screw fixing hole is provided on the fixing block 2; the support rod 1 is vertically inserted into the screw fixing hole, and the box cap 4 is fixed to the support rod 1 by screws 3 inserted on the side of the fixing block 2.

[0037] Specifically, the fixing block 2 is provided with a screw fixing port and a nut hole corresponding to the screw 3. The nut hole is connected to the screw fixing port. The support rod 1 is vertically inserted into the screw fixing port. After the screw 3 passes through the nut hole, its top abuts against the support rod 1, thereby realizing the purpose of the cap 4 being movably installed on the support rod 1.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
